Can people with chronic dry eyes get a laser eye surgery? What’s your experience?
In general, people
with pre-existing dry eye problems should avoid laser vision correction such as
LASIK. That is because every single patient who has it done will experience at
least a transient further decrease in tear production afterwards. This is due to
the unavoidable damage to sensory nerves in the cornea from the laser
re-shaping. The lacrimal glands themselves are unaffected, but they are getting
a muted signal as to how much dryness is present in the cornea so are not fully
responding to the need . Fortunately, the nerves do regenerate but it is
estimated that it takes as long as a year or two for this to finish.
